The diagnosis of ductal carcinoma in situ (DCIS) is increasing, although to the authors' knowledge there is no consensus regarding optimal treatment. This analysis of women treated with breast-conserving surgery (BCS) evaluated the impact of radiation therapy (RT) in patient outcomes. ⋯ Among a population-based cohort, RT was found to significantly reduce the risk of second events in the ipsilateral breast, particularly invasive tumors, although not to the extent reported in clinical trials.

Social factors influence cancer treatment choices, potentially affecting patient survival. In the current study, the authors studied the interrelations between marital status, treatment received, and survival in patients with glioblastoma multiforme (GM), using population-based data. ⋯ Unmarried patients with GM presented with larger tumors, were less likely to undergo both surgical resection and postoperative RT, and had a shorter survival after diagnosis when compared with married patients, even after adjustment for treatment and other prognostic factors.

Intraductal papillary mucinous tumors (IPMT) account for 5% of pancreatic neoplasms. Preoperative identification is important because of their frequent multifocal or diffuse involvement in pancreatic ducts, which makes extensive surgery necessary even in benign cases. To the authors' knowledge, the cytologic features of this entity in fine-needle aspiration biopsy (FNAB) specimens have seldom been described and are poorly standardized. ⋯ The most common features of IPMT were extracellular mucin and sheets of mucinous epithelium. Papillae and nuclear grooves were not consistently found. Nonmucinous epithelium, severe atypia, single atypical cells, and irregular clusters indicated a high probability of malignant transformation. Even in the absence of atypia, a clinically significant diagnostic orientation can be established in most cases on the basis of the characteristic cytologic picture.

Surgical resection of lung metastases is widely accepted in osteosarcoma patients. Few data exist on treatment of recurrent pulmonary metastases. The authors of the current study retrospectively analyzed patients with osteosarcoma who received surgery for recurrent lung metastases. ⋯ The authors concluded that patients persistently free of the primary osteosarcoma who developed recurrent resectable metastatic disease of the lung should be considered for reoperation a second, third, or fourth time, as these patients had similar DFI curves after five-years.

Randomized Controlled Trial Multicenter Study
Quality of life among patients with Stage II and III breast carcinoma randomized to receive high-dose chemotherapy with autologous bone marrow support or intermediate-dose chemotherapy: results from Cancer and Leukemia Group B 9066.
The objective of this study was to compare the quality of life (QOL) after treatment among patients who had breast carcinoma with multiple positive lymph nodes. The patients were randomized to receive either high-dose chemotherapy with autologous stem cell support (HDC) or intermediate-dose chemotherapy (IDC) in the adjuvant setting. ⋯ Patients who received more intensive adjuvant therapy experienced transient declines in QOL. By 12 months after therapy, QOL was comparable between the 2 arms, regardless of therapy intensity, and many QOL areas were improved from baseline.
